The invention relates to a servo tipper for a continuous casting production line of aluminum ingots, and aims to improve the stability of an aluminum ingot turning mechanism. The servo tipper consists of turning mechanisms which are symmetrically arranged on the left and right sides of a cooling conveyer. After an aluminum ingot to be turned 84 reach a turning station, a first cylinder 14 fixed on a left box 4 and a second cylinder 70 fixed on a right box 42 simultaneously acts to respectively drive a left turntable 25 and a right turntable 59 to do relative motion so as to clamp the aluminumingot 84; after the aluminum ingot 84 is clamped, a servo motor 72 acts to transmit motion and power to a fifth gear 76 which is arranged on a driving shaft 74; the fifth gear 76 are meshed with a fourth gear 64 and a sixth gear 80 at the same time so as to transmit the motion and the power in two paths, wherein one path is that the fourth gear 64 drives the right turntable 59 to intermittently rotate, and the other path is that the sixth gear 80 drives a sixth shaft 79 to rotate; the motion and the power are transmitted to a third shaft 6 through a second universal joint 46, a synchronizing shaft 38 and a fist universal joint 37, and are finally transmitted to a first gear 20 through a third gear 5 arranged on the third shaft 6 and a second gear 9 arranged on a second shaft 12; and the first gear 20 drives the left turntable 25 to synchronously rotate around an axis OO' by 180 degrees with the right turntable 59 so as to turn the aluminum ingot 84.
